Interface AbstractPhysicalDevice.BankReadTagProcessor

All Known Subinterfaces:

AbstractPhysicalDevice.BankTagProcessor, AbstractPhysicalDevice.EPCglobalClass1Gen2TagProcessor

Enclosing class:

AbstractPhysicalDevice

public static interface AbstractPhysicalDevice.BankReadTagProcessor

TagProcessors should implement this interface if the device can read data from memory banks on the associated tag.

Method Summary

ReadDeviceOpReport

readMemoryBank(String bank, int offset, int length)

Method Detail

readMemoryBank

ReadDeviceOpReport readMemoryBank(String bank,
                                  int offset,
                                  int length)
                                  throws IOException,
                                         AbstractPhysicalDevice.TagResultException

Parameters:

bank - the memory bank to read data from. See EPCGen2Util for helper methods to convert this bank name into an EPCglobal Class 1 Gen 2 standard bank number. Other tag types may define their own values for this bank.

offset - the offset of the memory extent to read from within the named bank

length - the length of data to read (0 < length <= 128)

Returns:

the ReadDeviceOpReport containing the results of the read operation. Data returned in the report must be a long array of length 1 or 2.

Throws:

IOException - if there is an IO error attempting to communicate with the device

AbstractPhysicalDevice.TagResultException - if there is an error reading the value from the tag. See AbstractPhysicalDevice.TagResultException.
